Is this a good idea?

If you don't work on your car, the cost of changing head gaskets will more than likely be more than $500.

damn, its a good thing I know how to change mine, cause I would be out ALOT of money on headgaskets by now!

$500 is about right for a dyno tune/chip burn, maybe a little more depending on location. For something you will be driving a ton, which it sounds like you will, I would definately reccomend getting the tune spot on before you go beating on it. I guess I should take my own advice

6-8psi on your GT's stock internals will be fine, but the HP bug WILL bite you, and you'll keep wanting more and more.... trust me
